Don't think Friday reveals are often, but I would like to point out that the colosseum was officially revealed Friday, November 13th. That had a teaser a few days before. But TLG also often from my knowledge has done many teasers the day before the reveal like the Question Block which had a teaser on the 8th and then was revealed on the 9th. If promobricks is correct in saying it will be revealed this week, which I could believe, Id say today (Thursday) we may get a teaser if they do one at all then a Friday reveal.
